Was your haematoma of the placenta missed or mismanaged — and could it be medical negligence?

Was your haematoma of the placenta missed or mismanaged — and could it be medical negligence?

Tagline: When a bleed behind the placenta, also known as haematoma of placenta, goes undetected or untreated, the harm to mother and baby can be profound — and the question of whether proper care was given deserves a clear answer.
You may have been told that what happened was just “one of those things.” You may have been sent home after bleeding, only for something to go seriously wrong later. You may have lost a pregnancy, or your baby was born with injuries, and no one has ever properly explained why. If a haematoma of the placenta was involved — or if you wonder whether it was missed entirely — you are not alone in asking these questions. What happened to you matters, and understanding it is the first step.
What Should Have Happened: The Standard of Care Pathway for Placental Haematoma
STEP 1 Symptoms reported (bleeding, pain, cramps) STEP 2 Urgent ultrasound ordered and reviewed STEP 3 Haematoma identified and classified by size STEP 4 Monitoring plan set (serial scans, rest, review) STEP 5 Escalation if worsening: hospital admission / delivery

If any of these steps was skipped — for example, if your bleeding was not investigated with an ultrasound, or if a haematoma was found but no monitoring plan was put in place — that gap may be relevant to whether the standard of care was met.

Understanding haematoma of the placenta: what normally happens

A haematoma of the placenta is a collection of blood that forms between the placenta and the wall of the uterus. The placenta is the organ that grows during pregnancy to supply oxygen and nutrients to the baby. When blood pools in or around it, the placenta may not work as well as it should.

There are different types. A subchorionic haematoma forms between the placenta and the outer membrane of the pregnancy sac. A retroplacental haematoma forms directly behind the placenta, between the placenta and the uterine wall. Retroplacental haematomas are generally considered more serious because they can interfere more directly with blood flow to the baby.

Many haematomas are found during routine ultrasound scans. Some cause bleeding or cramping. Others cause no symptoms at all. When a haematoma is found, the standard approach involves careful monitoring. This usually means repeat ultrasound scans to check whether the haematoma is growing, shrinking, or staying the same. Doctors also monitor the baby’s growth and wellbeing. In more serious cases, hospital admission or early delivery may be recommended.

Patients are generally told to rest, avoid strenuous activity, and report any new or worsening symptoms. The level of concern depends on the size of the haematoma, how far along the pregnancy is, and whether the baby shows any signs of distress.

When things start to go wrong

Not every haematoma leads to a serious outcome. Many resolve on their own. But some do not, and when warning signs are missed or dismissed, the consequences can be severe.

There is a difference between an expected complication — something that can happen even with good care — and a harm that results from a failure to act. Understanding that difference is important.

The following are red flags that should prompt urgent review:

  • Heavy or increasing vaginal bleeding during pregnancy
  • Severe abdominal pain or cramping that does not settle
  • A sudden reduction in the baby’s movements
  • A haematoma that is growing on repeat scans
  • Signs of placental abruption — where the placenta begins to separate from the uterine wall
  • Abnormal results on a cardiotocograph (CTG), which is a test that monitors the baby’s heart rate
  • Maternal symptoms such as dizziness, rapid heart rate, or low blood pressure suggesting significant blood loss
  • A haematoma larger than 25–50% of the placental size

When these signs appear, the standard of care requires prompt action. Waiting, dismissing symptoms, or failing to escalate can turn a manageable situation into a catastrophic one.

A common pattern — where care can break down

Across cases involving placental haematoma, certain failures appear again and again. These are not rare or unusual. They reflect patterns in how this condition is sometimes managed poorly.

No investigation of reported bleeding. A pregnant woman reports vaginal bleeding to her GP or midwife. No ultrasound is arranged. She is told it is likely implantation bleeding or a minor issue. The haematoma is never identified until something goes seriously wrong.

Delayed diagnosis after symptoms are present. Symptoms are noted but the ultrasound is not arranged urgently. Days pass. The haematoma grows. By the time it is found, the placenta has already been compromised.

Dismissed symptoms at a hospital presentation. A woman presents to an emergency department or maternity unit with pain and bleeding. She is assessed briefly and sent home without imaging. Her concerns are not taken seriously. This is a pattern that affects many women, and it has been documented in Australian safety reviews.

Failure to refer to a specialist. A GP or general obstetrician identifies a haematoma but does not refer the patient to a maternal-fetal medicine specialist, even when the haematoma is large or the pregnancy is high-risk. The patient does not receive the level of monitoring her situation requires.

Failure to treat or escalate. A haematoma is identified and documented, but no monitoring plan is put in place. There are no follow-up scans. No one reviews whether the haematoma is growing. The patient is left without guidance about what to watch for.

Inadequate aftercare following a known haematoma. The patient is discharged from hospital after a haematoma is found, but no clear plan is given. She does not know when to return, what symptoms to watch for, or who to contact if things change. The gap in communication leads to a delayed response when her condition worsens.

The Australian Commission on Safety and Quality in Health Care has published guidance on the importance of clear communication and informed consent in maternity care. When patients are not properly informed about their condition or their options, that failure can itself be part of a negligence claim.

Why this matters legally

Duty of care is the legal obligation a health professional has to take reasonable steps to avoid causing harm to their patient. Every doctor, midwife, and hospital that treats a pregnant woman owes her — and her baby — a duty of care.

Not every bad outcome in pregnancy is negligence. Pregnancies can go wrong even when every clinician does everything right. The law does not require perfection. It requires that the care given met the standard of a reasonably competent professional in the same field, acting in the same circumstances.

What “reasonable care” means in a placental haematoma case depends on the specific facts. It includes whether symptoms were properly investigated, whether imaging was arranged in a timely way, whether findings were correctly interpreted, and whether the response to those findings was appropriate.

When a clinician’s actions fall below that standard — and that failure causes harm that would not otherwise have occurred — the law in NSW may recognise a claim for medical negligence. For a broader overview of how these claims work, visit Reframe Legal — Medical Negligence.

This is a general educational framework only. Each case is assessed on its individual facts.

When haematoma of the placenta may amount to medical negligence

The NSW Civil Liability Act 2002 is the main law in New South Wales that sets out how negligence claims against health professionals are assessed. It requires courts to consider what a reasonable professional in the same field would have done in the same situation.

The following scenarios may be relevant to a negligence claim. Each links a factual situation to a potential legal failure.

If you reported bleeding and no ultrasound was arranged: A clinician who fails to investigate a reported symptom that could indicate a placental haematoma may have breached the standard of care. Bleeding in pregnancy is a known warning sign that requires investigation.

If a haematoma was found but no monitoring plan was put in place: Finding a haematoma and then doing nothing about it is not consistent with accepted practice. A failure to arrange follow-up scans or provide clear guidance may constitute a breach.

If the haematoma grew and no one escalated care: Serial scans exist precisely to detect growth. If scans showed a growing haematoma and no clinician changed the management plan, that inaction may be legally significant.

If signs of fetal distress were present and delivery was not expedited: When a baby shows signs of distress — through abnormal CTG readings or reduced movements — and the clinical team does not act promptly, the delay itself may be the cause of harm.

If you were discharged without adequate information: Sending a patient home without explaining what to watch for, or without a clear plan for follow-up, may breach both the duty of care and the obligation to obtain informed consent to a management approach.

When harm becomes long-term or permanent

The consequences of a missed or mismanaged placental haematoma can extend far beyond the pregnancy itself. They can shape the rest of a person’s life.

Physical consequences may include pregnancy loss, premature birth, placental abruption — which is when the placenta separates from the uterine wall before birth — and significant maternal haemorrhage. Babies born after a poorly managed haematoma may have suffered oxygen deprivation, which can cause cerebral palsy, developmental delays, or other neurological injuries. Mothers may face long-term complications from blood loss, emergency surgery, or hysterectomy.

Psychological consequences are often profound and underestimated. Grief after pregnancy loss is not a minor event. Trauma from an emergency delivery, from watching a baby fight for life in a neonatal intensive care unit, or from living with the knowledge that something went wrong — these experiences cause lasting psychological harm. Post-traumatic stress disorder, depression, and anxiety are common in women who have experienced serious obstetric complications.

Financial consequences accumulate over time. A baby with a permanent disability requires ongoing therapy, specialist care, modified schooling, and in many cases, lifelong support. A mother who cannot return to work because of her own injuries or because she is the primary carer for a child with complex needs faces years of lost income. These costs are real, and they are calculable.

What compensation can cover in haematoma of the placenta cases

In NSW, compensation in a medical negligence claim can cover pain and suffering, lost income, the cost of past and future medical treatment, and the cost of care — both professional care and the care provided by family members.

Level of harm Typical compensation range
Moderate injury $50,000–$150,000
Serious injury $150,000–$500,000
Severe / life-changing injury $500,000+

Each case is assessed on its own facts. These figures are general ranges only.

Time limits apply in NSW. In most cases, a person has three years from the date they knew — or ought reasonably to have known — that they had a potential claim. For children, different rules may apply. Acting within the time limit is important.

Bringing it together — do the pieces fit?

You do not need to be a lawyer or a doctor to start asking the right questions. The following questions can help you think through what happened in your situation.

  • Did you report symptoms — bleeding, pain, reduced fetal movement — and were they properly investigated?
  • Was an ultrasound arranged promptly, or was there a delay?
  • Was a haematoma found? If so, were you told about it and given a clear monitoring plan?
  • Were follow-up scans arranged and reviewed?
  • Did your condition or your baby’s condition worsen, and did the clinical team respond appropriately?
  • Were you given enough information to understand your situation and make decisions about your care?
  • Did the outcome — for you or your baby — match what you were told to expect?

If the answers to these questions leave you with doubts, those doubts deserve to be examined carefully. For a detailed explanation of how negligence claims are assessed in NSW, visit Reframe Legal — How Medical Negligence Claims Work in NSW.

You do not need certainty to understand your position

Many people who have experienced a serious pregnancy complication spend months — sometimes years — wondering whether what happened was avoidable. They second-guess themselves. They wonder if they are being unfair to the doctors and midwives who cared for them. They feel guilty for even asking the question.

That self-doubt is normal. It does not mean your concerns are wrong. It means you are human.

Legal clarity does not come from certainty. It comes from examining the facts. A lawyer who understands medical negligence can look at your records, compare what happened to what should have happened, and give you an honest assessment. You do not need to know the answer before you ask the question.

It is also worth knowing that you have the right to make a formal notification about a health practitioner’s conduct. This is separate from a legal claim. AHPRA — How we handle notifications about practitioners explains how that process works and what AHPRA can and cannot do.

If you are also thinking about questions of consent — whether you were properly informed about the risks of your management plan — that is a separate but related legal issue. You can read more at Reframe Legal — Informed Consent and Medical Negligence.

About the lawyer behind this article

Dr Rosemary Listing — Medical Negligence Lawyer

Dr Rosemary Listing is an Australian lawyer with a PhD focused on medical negligence. She works with people in New South Wales who have experienced serious harm in the context of medical care, including harm arising from obstetric and maternity complications.

Placental haematoma cases present a particular challenge because the harm often does not come from the haematoma itself — it comes from the failure to detect it, monitor it, or act on it in time. In Dr Listing’s experience, the gap between what was done and what should have been done is often where the legal question lies.

The people who seek Dr Listing’s guidance are not primarily looking to blame anyone. They are looking for clarity. They want to understand what happened, whether it should have happened, and what their options are. That is a reasonable thing to want, and it is the starting point for every assessment she undertakes.
